A loop lifter is located between roll stands (2',2''), and is placed against the metal strip, so that a roller (6) of loop lifter is contacted with metal strip. The roller is connected to a speed measuring device (7) through flexible shaft (8), so that rotational speed (n) of roller is detected. The detected speed is fed to control unit (9) of rolling mill.</p> |
